Which movement is this?

Hi all

I am desperately trying to identify the movement of one of my favorite (though relatively cheap) watches. The movement seems to be broken and I would like to repair or replace it. But in order to do so, I need to find out which movements would be suitable to replace it.

Unfortunately there is no ID or number on the movement itself. I disassembled the watch already and the movement had to be removed via the front, thus I had to remove the pressed bezel. I also removed the clockface and the diameter of the movement is approximately 32mm. The movement drives hour, minute and second hands as well as three manual hands for date (at 9),  weekday (at 3) … those  are steered by two manual buttons at the right side next to the crown and a third hand at 6.

Can anyone identify the movement based on this information and the pictures attached? Would any additional information be required?
